Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a high-efficiency gas-liquid separator device. Background Technology

[0002] Industrial production processes generate a large amount of waste gas, which often requires purification before being discharged. Waste gas purification mainly targets industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust purification, organic waste gas purification, odor purification, acid and alkali waste gas purification, and chemical waste gas purification. Accordingly, a large number of waste gas purification equipment have appeared on the market, with spray purification towers being one type.

[0003] Existing purification towers are not very effective at adsorbing and treating particulate matter and impurities in exhaust gas. Impurities are prone to redispersing, and gas-liquid separation is not thorough enough. If harmful particulate matter is encapsulated by liquid droplets, it is not easy to purify and treat, thus affecting the efficiency of exhaust gas purification.

[0004] Therefore, there is a need for a high-efficiency gas-liquid separator device that helps improve the efficiency of waste gas purification. Utility Model Content

A liquid collection port adapted to the upper surface of the partition is provided on the cylinder wall of the high tower. A baffle plate structure is provided at the top of the uppermost air guide cylinder.

[0007] Furthermore, the liquid guide plate is a conical cylinder structure fixedly connected to the outer wall of the air guide cylinder, with the upper end of the conical cylinder being smaller and the lower end being larger.

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Reference Figures 1-6As shown, this embodiment provides a high-efficiency gas-liquid separator device, including a high tower 3 and a packing adsorption structure disposed within the high tower 3. Activated carbon particles are disposed within the packing adsorption structure. The bottom of the high tower 3 is provided with an air inlet 1, and the top of the high tower 3 is provided with a tail gas outlet 9. A gas-liquid separator 6 is disposed below the packing adsorption structure within the high tower 3. The gas-liquid separator 6 includes a partition plate 12 with a central hole, multiple air guide cylinders 13 with progressively decreasing diameters from bottom to top disposed at the central hole of the partition plate 12, and an air passage mesh plate 10 disposed between two adjacent air guide cylinders 13. A liquid guide plate 11 connected to the outer wall of the uppermost air guide cylinder 13 is disposed above the air passage mesh plate 10. A liquid collection port 5 adapted to the upper surface of the partition plate 12 is provided on the cylinder wall of the high tower 3. The partition plate 12 is a conical cylinder structure, and a baffle plate structure 14 is provided at the top of the uppermost air guide cylinder 13.

[0029] In this high-efficiency gas-liquid separator device, a packing adsorption structure is set inside the high tower 3, through which the activated carbon particles of the packing adsorption structure adsorb harmful substances in the waste gas; and a gas-liquid separator 6 is set inside the high tower 3 to separate the liquid in the waste gas. The harmful substances in the waste gas are separated out along with the gas-liquid separation. The waste gas after preliminary treatment then enters the packing adsorption structure for further treatment, avoiding the influence of water vapor in the waste gas on the adsorption of harmful substances by the packing adsorption structure, thereby improving the adsorption efficiency of the packing adsorption structure for harmful substances in the waste gas.

[0030] The exhaust gas flows upward and passes through the perforated plate 10 in the gas-liquid separator 6. The water vapor in the exhaust gas is partially separated and forms water droplets, which drip downward to the bottom of the tower 3. After the exhaust gas flows out from the edge of the perforated plate 10 to the outside of the gas guide tube 13, it is blocked by the liquid guide plate 11 on the outer wall of the upper gas guide tube 13. The water vapor in the exhaust gas forms water droplets when it comes into contact with the lower surface of the liquid guide plate 11. The water droplets flow downward along the liquid guide plate 11 and drip onto the upper surface of the lower liquid guide plate 11. Finally, they flow onto the baffle plate 12, and the waste liquid collected on the baffle plate 12 can be discharged from the liquid collection port 5.

[0031] Specifically, refer to Figures 1-3 The liquid guide plate 11 is a conical cylinder structure fixedly connected to the outer wall of the air guide cylinder 13. The upper end of the conical cylinder structure is small and the lower end is large. The cylinder wall of the conical cylinder has a slope, which facilitates the downward flow of water droplets formed on the cylinder wall.

[0032] Specifically, refer to Figures 1-3 The edge of the perforated plate 10 is adapted to the opening of the air guide tube 13 located below it. The perforated plate 10 is provided with multiple mesh holes. When the water vapor in the exhaust gas comes into contact with the perforated plate 10, it will form water droplets that fall downwards, thus performing preliminary separation of the liquid in the exhaust gas.

[0033] Specifically, refer to Figures 1-3 Inside the tower 3, below the gas-liquid separator 6, there is a first wire mesh demister 4. The first wire mesh demister 4 is used to remove mist (droplets) entrained in the gas, recover expensive mist droplets (valuable materials), or purify the gas to reduce impurities in the gas. It is a conventional structure that is easy to purchase. In this embodiment, the first wire mesh demister 4 can separate the mist in the exhaust gas, which helps to improve the efficiency of water vapor in the exhaust gas being adsorbed by the gas-liquid separator 6 above the first wire mesh demister 4, and helps to improve the adsorption efficiency of harmful substances in the exhaust gas by the packing adsorption structure.

[0034] Specifically, refer to Figures 1-3 Inside the tower 3, above the gas-liquid separator 6, a second wire mesh demister 7 is provided. The second wire mesh demister 7 is used to remove mist (droplets) entrained in the gas, recover expensive mist droplets (valuable materials), or purify the gas to reduce impurities in the gas. It is a conventional structure that is easy to purchase. In this embodiment, the second wire mesh demister 7 can separate the exhaust gas after the water vapor has been separated by the gas-liquid separator 6, which helps to improve the efficiency of the adsorption of harmful substances in the exhaust gas by the packing adsorption structure above the second wire mesh demister 7.

[0035] Specifically, refer to Figure 1 The tower 3 is provided with a waste liquid chamber 2 located below the air inlet 1. The bottom end of the waste liquid chamber 2 is provided with a waste outlet. Water droplets formed after passing through the gas-liquid separator 6 fall into the waste liquid chamber 2.

[0036] Specifically, refer to Figures 4-6 The baffle structure 14 includes multiple parallel-spaced water collection troughs 15 located at the opening of the uppermost air guide cylinder 13. An inverted V-shaped baffle 16 is provided between two adjacent water collection troughs 15. The lower surfaces of both sides of the inverted V-shaped baffle 16 are provided with raised blocks 22 connected to the sides of the water collection trough 15. A gap is provided between the lower surfaces of both sides of the inverted V-shaped baffle 16 and the top of the trough walls on both sides of the water collection trough 15 for waste gas to pass through. In this embodiment, the waste gas passes through the perforated mesh plates 10 inside the multiple air guide cylinders 13. After gas-water separation, a portion flows upward to the bottom of the water collection tank 15. After being blocked by the bottom wall of the water collection tank 15, the water vapor in the exhaust gas can be separated again. Then, it flows upward from the gap between the two water collection tanks 15 to the bottom of the inverted V-shaped baffle 16. After being blocked by the inverted V-shaped baffle 16, the water vapor in the exhaust gas is separated again. The water droplets formed on the lower surface of the inverted V-shaped baffle 16 flow into the water collection tanks 15 on both sides, and then flow out from both ends of the water collection tanks 15 to the liquid guide plate 11 at the top of the air guide tube 13, and finally converges to the baffle 12.

[0037] Specifically, refer to Figures 5-6The water collection tank 15 includes a V-shaped groove 17 with both ends through it and side plates 18 on both sides of the V-shaped groove 17. The shim block 22 is connected to the top of the side plate 18. The outer surfaces of both sides of the V-shaped groove 17 are also inclined structures, forming a funnel structure between the two water collection tanks 15, which facilitates the exhaust gas to enter the gap between the two water collection tanks 15.

[0038] Specifically, refer to Figure 1 The tower 3 has an air intake cylinder 19 at its bottom, connected to the air inlet 1, extending horizontally into the tower 3. The bottom of the inner end of the air intake cylinder 19 has an opening 21, at which multiple evenly spaced vertical plates 20 are arranged. These vertical plates 20 are perpendicular to the centerline of the air intake cylinder 19, and their height gradually increases from the outside to the inside. In this embodiment, when exhaust gas enters the air intake cylinder 19, the water vapor in the exhaust gas is initially separated by the multiple vertical plates 20 before falling into the waste liquid chamber 2 below.

[0039] Working principle:

[0040] The exhaust gas enters the intake cylinder 19 from the intake port 1. After being blocked by multiple vertical plates 20 inside the intake cylinder 19, the water vapor in the exhaust gas can be initially separated.

[0041] Then the exhaust gas flows upward and undergoes preliminary demisting through the first wire mesh demister 4;

[0042] The exhaust gas then continues to flow upwards, passing through liquid separator 6 to separate the water vapor in the exhaust gas;

[0043] The exhaust gas then continues to flow upwards and passes through the second wire mesh demister 7 for further demisting.

[0044] Finally, the exhaust gas flows upward to the packing adsorption structure, where activated carbon particles adsorb harmful substances and purify the exhaust gas.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
